Answer:

Step-by-step explanation:

f(x)=-4x+2

g(x)=x²+1

(gof)(x)=g(f(x))=g(-4x+2)=(-4x+2)²+2=16x²-16x+4+2=16x²-16x+6

(gof)(3)=16(3)²-16(3)+6=144-48+6=150-48=102

Answer:

$d = \frac{4 - 3c}{c + 1}$

Step-by-step explanation:

To make d the subject of formula, we need to rearrange the equation such that we arrive at d= _____.

$c = \frac{4 - d}{d + 3}$

Remove the fraction by multiplying (d +3) on both sides:

$c(d + 3) = 4 - d$

Expand:

$cd + 3c = 4 - d$

Bring all the d terms to one side and move the others to the other side of the equation:

$cd + d = 4 - 3c$

Factorise d out:

$d(c + 1) = 4 - 3c$

Divide by (c +1) on both sides:

$d = \frac{4 - 3c}{c + 1}$

Dvinal [7]

Answer: the trip (one-way) that Alan made on Saturday was 63 miles.

Step-by-step explanation:

Let x represent the distance of the trip that Alan made on Saturday.

Let t represent the time that it took Alan to make the trip on Saturday.

On Saturday, Alan traveled North along minor roads averaging 36 mph to visit a friend.

Distance = speed × time.

Therefore, distance travelled on Saturday would be

x = 36 × t = 36t

On Sunday, he traveled East along main roads averaging 60 mph to visit his mother. The trip to visit his mother was 24 miles longer and took 18 minutes(18/60 = 0.3 hours) less. This means that the distance travelled would be

x + 24 and the time spent would be t - 0.3 hours.

Distance travelled on Sunday would be

x + 24 = 60(t - 0.3)

x + 24 = 60t - 18 - - - - - - -- - - 1

Substituting x = 36t into equation 1, it becomes

36t + 24 = 60t - 18

60t - 36t = 24 + 18

24t = 42

t = 42/24 = 1.75

x = 36t = 36 × 1.75

x = 63 miles
